There is an old story of an astrologer who came to a king and said, “You are going to die in six months.” The king was frightened out of his wits and was almost about to die then and there from fear. But his minister was a clever man, and this man told the king that these astrologers were fools. The king would not believe him. So the minister saw no other way to make the king see that they were fools but to invite the astrologer to the palace again. There he asked him if his calculations were correct. The astrologer said that there could not be a mistake, but to satisfy him he went through the whole of the calculations again and then said that they were perfectly correct. The king’s face became livid. The minister said to the astrologer, “And when do you think that you will die?” “In twelve years”, was the reply. The minister quickly drew his sword and separated the astrologer’s head from the body and said to the king, “Do you see this liar? He is dead this moment.”
